To all whom it may concern:

Be it known that 1, JOHN JOSEPH COOPER, a subject of the King of Great Britain, and resident of 120 .Queen Victoria street, London, E. 0., England, have invented certain new and useful Improvements in Type- WVriting-Wlachine Copy-Holders, of which the following is a specification.

The bject of this invention is to provide simple, handy, and inexpensive means for enabling a strip of paper or like material to be supported, and moved lengthwise intermittently at will past a given point; the invention being designed more particularly with a view to enabling a telegraph tape, or

similar narrow strip of material bearing an inscription, to be supported upon a type- 7 writing machine in a convenient positionto serve as a copy for the typist, and to be fed, lengthwise, transversely of the machine stepby-step with the minimum of trouble.

According to this invention the strip, supported in a channeled guide whose side walls are undercut or similarly shaped to prevent the strip from rising out of the guide, is propelled lengthwise of the guide at will by means of a traveler slidable on the guide and adapted, when moved in the direction of feed, to bear uponthe strip with a yielding pressure sufficient to cause the strip to move with the traveler but,- when moved in the opposite direction, to slide over thestrip without imparting motion thereto.

In the accompanying drawings, which illustrate a convenient form of the inven tion as applied for the purpose of supporting and feeding a telegraph tape the message on which is to be transcribed by a typist, Figure 1 is a front elevation, Fig. 2 is an end elevation, and Fig. 3 is a plan view (looking in the direction of the arrow in Fig. 2), showing so much of the typewriting machine as is necessary for the purpose of explaining the invention. Figs. 4, 5 and, 6 are detail views of the traveler, drawn to a larger scale; Fig. 4 being a front elevation with the guide-bar in longitudinal section, Fig. 5 an end elevation with the guide-bar in cross section, and Fig. 6 another end ele-V vation, viewed in the opposite direction to Fig. 5, with the guide-bar omitted.

In the arrangement illustrated, a hori zontal guide A for the tape B is supported onbrackets C projecting from thefront of of the guide.

the frame D of the typewriting machine so that the guide A extends, transversely of the machine, in a convenient position above the keyboard and preferably, as shown, in front of and at the same inclination as the usual fixed scale of lengths E; the screws (Z- which secure the brackets C to the frame D serving also to attach thereto the horizontal bar 6 which supports the scale E. (This scale and its supporting bar are omittedin Fig. 1.) The guide A is preferably formed from a strip of thin sheet metal whose margins a, 66 (Fig. 5) .are bent upward and inturned toward one another so as, while permitting the tape B to slide easily along the channel thus constituted, to prevent the tape from buckling and rising out The guide A, formed as described, is stiffened by a backing formed by what may be called a foundation-bar F of corresponding length and of somewhat greater width than the guide, fixed directly to the brackets, the guide itself being attached to the rigid foundation-bar by rivets or other suitable means.

The traveler comprises a carriage provided with an automatic gripping'device and fittedjto slide-easily to-and-fro on the projecting marginal portions f, f of the foundation-bar'F as rails, the length of travel of the carriage being limited by stops F, f fixed a predetermined or adjustable distance apart on the bar. The carriage is most conveniently formed of a pair of cheek-plates G, G held together (above the level of the guide A) by cross-stays g, the cheek-plates being grooved longitudinally on their inner faces as at, 9 (Fig. 6) so that the carriage, while freely slidable on the rails 7 which fit into the grooves, is irremovable from the track except by being slid off it at one end or the other thereof.

Upon a transverse axis 71, carried by the carriage is pivoted an actuator in the form of a three-armed lever whereof one arm H extends upward so as to constitute a handle operable by the finger of the typist, while another arm H extends lengthwise of the guide in the direction of feed (2'. 0-. toward the left in Figs. 1, 3 and 4), and a third arm H extends in the opposite direction to H so as to limitthe oscillation of the lever about its fulcrum h; the arm H forming a tape-feeding grip carrying at its extremity a soft pad 7& (preferably of cork) adapted to contact with the tape 13 and press it lightly against the bottom of the guide A.

The arrangement is such that when the finger, in contact with the lever-handle H, moves the traveler in the direction of feed, the arm H will grip the tape B against the bottom of the guide A, through the medium of the pad 71, so lightly as merely to insure such frictional contact between lever and tape as is necessary in order that the tape shall be propelled along with the traveler, but that on the motion of the traveler being reversed, the pad it will be lifted out of contact with the tape so that the latter will remain stationary while the traveler is moved backward in readiness to propel a fresh length of tape on the feed-motion being repeated.

1 claim 1. The combination of a channel guide for a telegraph strip, a device slidable along the guide, said-device including an actuator and means dependent upon a force applied to said actuator in a direction to advance said device for causing the same to bear upon the strip with a yielding pressure suflicient to cause the strip to move with said device, said means being ineffective upon said strip when said device is moved by said actuator in the opposite direction.

2. The combination of a telegraph tape guide, a carriage, and a lever pivoted on the carriage, and having an arm which constitutes a handle, and having another arm extending in the direction of feed, to exert pressure upon the tape, and provided with a pad of soft material to feed the tape.

8. The combination with a telegraph tape guide, of a traveler, an actuator by which said traveler may be moved manually to and fro along the guide, and means dependent upon the manual operation of thetraveler by said actuator to move the traveler in only one direction for advancing the tape along the guide, the traveler movable along the tape in the opposite direction, whereby the tape may be fed step by step in one direction by moving said traveler to and fro.

4. The combination with a telegraph tape guide, of a traveler, a handle connected to said traveler to move the same to and fro along the guide, and a tape-feeding grip released by said handle when retracting the traveler, but caused by said handle to grip the tape and advance the same when said handle is advancing said traveler, said grip movable along a fresh portion of the tape at each retraction of the traveler to a new gripping position on the tape, so that the V tape is fed step by step in one direction.

5. The combination with a telegraph tape channel or guide, of a manually movable traveler, an actuator carried thereby by which the traveler 1s movable in one direction along said channel independently of the tape, and means dependent upon the movement of the traveler by said actuator in the opposite direction for advancing the tape along the channel, whereby the traveler may be advanced step by step in one direction by operating said actuator to move the traveler to and fro.

6. The combination with a telegraph tape channel or guide, of a manually movable traveler movable in one direction along said channel independently of the tape, and having means dependent upon the movement of the traveler in the opposite direction for advancing the tape along the channel, said channel having side walls formed to overhang the tape, for confining the same within the channel.

7 The combination with a telegraph tape guide, of means for feeding a continuous length of tape step by step along the guide, said means comprising a traveler, a grip pivoted upon said traveler to engage the tape, and a traveler-advancing handle connected to said grip to render the same effective only during the advance of the traveler.

8. The combination of brackets for attachment to a typewriting machine, a bar attached to said bracketsa tape-guide 0r channel upon said bar, a traveler fitted to slide upon said bar, and a lever pivoted upon said traveler and comprising both a tape-engaging friction arm and a projecting handle.

9. The combination of brackets for attachment to a typewriting machine, a bar attached to said brackets, a tape-guide or channel upon said bar, a traveler fitted to slide upon said bar, and a lever pivoted upon said traveler and comprising both a tape-engaging friction arm and a projecting handle, and also having a stop portion to limit the play of the lever when returning the traveler over the tape.

10. The combination of brackets for at tachment to a typewriting machine, a bar attached to said brackets, a tape-guide or channel upon said bar, a traveler fitted to slide upon said bar, and a lever pivoted upon said traveler and comprising both a tape-engaging friction arm and a projecting handle, said traveler comprising a pair of connected cheek plates fitted to said bar to slide thereon, and said lever being mounted between said cheek plates; said guide or channel also occupying a position between said cheek plates.
